America’s TV dad, Stephen Colbert, brought America’s TV cousin, Nick Kroll, to The Late Show to have an awkward conversation about puberty. Colbert and Kroll started off by talking about all the changes your body goes through during puberty, like growing body hair. When Colbert asked the “cool older cousin” whether he was getting body hair, he said, “Yeah, I can scrub a pot with my nip hair!” And if having “the talk” wasn’t hard enough, Kroll kept making Colbert crack up.

The laughs continued throughout the conversation, and Colbert completely lost it when Kroll explained his preferred contraceptive. “You can save $10 and just put a tooth-whitening strip on your peener — works great,” Kroll exclaimed. When Colbert urged people not to do that, Kroll said, “Do it. My penis has never been whiter.” That is when Colbert lost it, looking down in an attempt to hold back his laughter. But Kroll made it difficult when he added, “You gotta see it smile.” And while there was no useful information, at least everyone had a good laugh.
